Filed Dec. 26, 1955 INVENTOR 7 fie/1M1 3121015). 15' (WIDE Patented Nov. 24, 1936 UNITED STATES PATENT OFFICE BOOK BINDING CONSTRUCTION Application December 26, 1935, Serial No. 56,151 2 Claims. (01.28145) This invention relates to improvements in book binding constructions. It consists in a new combination of book covers, back panel, filler sheets, and ring binding means to hold the other parts together in book form while also serving as a hinge means for such parts, particularly for the covers and back panel.

The new construction is shown in its preferred form by the accompanying drawing, in which- Fig. 1 is a top plan of the book assembly in closed position;

Fig. 2 is a view looking at the book of Fig. 1 in the direction of the arrow in the latter figure;

Fig. 3 is a plan view of the back of the book when in open position;

Fig. 4 is a detail view of the two back panel parts slightly separated to indicate the manner of assembly;

Fig. 5 is a View of the hook without the back panel parts attached; and

Fig. 6 is a detail view at one end of the back panel parts indicating how the attachment is made.

To make up the new structure I preferably proceed as follows. Two book covers 3 and 4 are laid on the outside faces of the pack of book pages 5. This assembly has perforations 6 made along the binding margin. A helically coiled binding wire "I is threaded through these perforations. The back panel parts 8 and 9 are then laid respectively on the outside and on the inside of the cylinder formed by wire 1. The ends 10 of part 8 are bent over and clinched at the ends 9 as indicated in Fig. 6. The result is the bound book of Figs. 1 and 2.

This book, when closed as in Fig. 1, presents a book binding construction in which the back panel is positioned as in ordinary books, but between the side edges of the back panel and the covers the binding wire 1 forms the hinge construction, and all the pages of the book as well as the covers may turn freely on the same hinge construction. It is an extremely simple book construction and of good appearance.

As to some of the detail construction, I prefer to use the binding wire I in the form of a continuous helical coil from end to end of the book. This is a simple construction and there is no special work needed at the ends of the wire because they can lie in hidden and clamped relation to back panel parts 8 and 9. But instead of the continuous coiled wire I I may use other known forms of wire ring binding means, such as a series of spaced rings in parallel planes at right angles to the edges of the sheets. Such simple ring binding means are known, for example, in various pad constructions used for stenographers notebooks. While I prefer the coiled wire binding construction 1 I do not desire to limit my combination construction to that specific form for the element between the back panel and sheets including the covers. I have shown a simple means for assembling the parts, but of course many difierent specific means could be used without changing the broad plan of the combination as disclosed. I prefer the specific features of construction in the broad combination just as disclosed for the best practical use.

What I claim is:

1. A book binding construction comprising in combination a pack of book sheets with outside cover elements all loosely hung on a helically coiled wire threaded through perforations in their binding margin, a back panel shaped to lie against the back portions of said wire, a binding plate laid against the back and inside portions of said coiled wire with its ends attached to the ends of the back panel, all constructed for said coiled wire to be exposed as hinge portions between the edges of the covers and the edges of the back panel but to be completely covered at the back of the book by the back panel, when the book is opened out flat.

2. A pack of filler sheets bound at one margin with a one-piece series of closely spaced binding coils, in combination with book covers bound to the coils just as the sheets are bound and a back panel member separate from the covers and fastened against the back side of said coils to cover up that side of the one-piece binder element, said back panel having its edges when the book is closed spaced slightly from the inner edges of the book covers, the coils being thus exposed just enough between the back panel and covers to serve and appear as very narrow hinge bands, the book as a whole being substantially encased by covers and back panel with the narrow hinge bands helping to give a finished binding case effect to the book combination and yet allowing for economical manufacture.
